For years when I had the studio I used Speedotrons, big-heavy packs but powerful and durable. I was mostly a hot light guy so the strobe only got used when people were involved.
Fast forward to the new reality....the studio is gone, and I shoot entirely on location. I started by trying to continue to do the hot light thing but a dark space and plenty of power were uncommon in a standard factory environment. I know I had to go strobe.
Forget the speedos
I needed small. Even though many think they are silly I found the Alien Bees to perfect fit. They are small...I can hide them almost as easily as a Pepper. They are light, easy to pack, really durable and best of all the price almost makes them disposable. Not that you would need to do that since Buff's service is simply amazing and cheap. A head that crashes to the floor from the top of a 13 foot stand costs 75 bucks to repair, not counting the tube and model light.
We travel by mini van and space is still at a premium since we need to carry all the props to shoot two trailers a day. That means 18 plastic tubs of props plus computer and photo equipment. I carry 12- AB1600. I can get 5 heads, cords and 7" reflectors in Lightware V4000 view camera case. I do that times two. I also carry 2 AB1600 with a Vagabond Mini Battery in a Lightware MF1217. The 12 heads and the battery cost $4800.00 Not bad for a lot of lightweight light.
